Can you explain more about CCNA. I heard about it a lot. Need to sit for exam?
Often an added advantage for those who having it.

CCNA stand for Cisco Certified Network Associate, it's consider a fundamental paper to work in networking field...
U may also further ur study to CCNP and CCIE. Or on other networking field such as designing, voice and wireless...
CCNA consist of ICND1 and ICND2 or u may just take a composite paper which consists of both of them...
Generally, you need the certificate if u wish to work in networking environment...
Besides Cisco, there's also other big vendors like Juniper, Huawei, HP, 3COM... Although diff products use diff style of command lines.
But the networking concept behind and some of the protocols used are the same.
But if you wish to become a RF (Radio Frequency) engineer. Then u can skip networking cert.
Because if you have degree in electronics and it's better if majoring in telecommunication, then you may start your career as RF engineer lo.
